Other: The genus name, "Zigadenus", is derived from the Greek words “zugon” which means “yoke” and “aden” which means “gland or paired glands” describing the flowers. The species name, “vaginatus” means “sheath” which describes the leaves.
Zigadenus vaginatus is endemic to Grand, Kane, San Juan and Washington Counties in Utah. This plant is a C3 federal species of concern. C3 are taxa that are no longer being considered for listing as threatened or endangered species by the United States Fish and Wildlife Service. Although this C3 candidate is no longer officially considered for listing under the Endangered Species Act, the former candidate status is important historical information.
Yucca and aloe used to be in this family. The family is extremely complex. Some ornamentals and medicinally useful plants are in this family, but a few species, such as this one, are poisonous.
